ok so
walk off triple, while ure going up have like 5 buttons appear that you have to shoot before doing another triple, then shoot another like 7 buttons, then again triple + like 10 buttons, and after you shoot the last button gravity switches and you gotta ceiling triple kinda like abuq last, and maybe have another like 8 buttons you have to shoot in reverse gravity after the ceiling triple to open up the floor or something.
would be totally aids online but thats how we like them
and if you can make the buttons appear at random places that would be even more awesome
